Description

Technical Field

[0001] The utility model relates to the technical field of separation valves, and more specifically to an oxygen-making separation valve. Background Art

[0002] Oxygen concentrator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then distilled to separate it into oxygen and nitrogen. In general, since it is mostly used to produce oxygen, people are accustomed to calling it an oxygen concentrator. The household oxygen concentrator mainly has a four-way valve and a guide valve, which are mainly used for oxygen ventilation in the oxygen concentrator.

[0003] The existing four-way valve of the oxygen concentrator is installed inside the oxygen concentrator for use, and the four-way valve is mainly assembled by screws. Due to the small internal space of the oxygen concentrator, it is inconvenient to assemble and disassemble the four-way valve inside the oxygen concentrator. Therefore, during installation, the four-way valve needs to be assembled and then installed inside the oxygen concentrator. At the same time, during maintenance, the four-way valve needs to be dismantled as a whole for maintenance, which is inconvenient to operate, thereby reducing work efficiency and increasing work intensity.

[0004] In view of this, we propose an oxygen production separation valve. Utility Model Content

[0027] See also Figure 1-4 ,The utility model provides a technical solution:

[0028] An oxygen production separation valve comprises a first valve housing 1 and a second valve housing 2, a sealing block 3 is fixedly arranged on the lower side of the second valve housing 2, and an inner groove 5 is opened on the inner side of the second valve housing 2, two groups of sliders 7 are movably arranged on the inner side of the inner groove 5, and a connecting block 9 is fixedly arranged on the lower side of the two groups of sliders 7, and the connecting block 9 movably penetrates the sealing block 3 and extends to the lower side, and a positioning block 10 is fixedly arranged on the outer side of the connecting block 9 located at the lower side of the sealing block 3, a mounting block 8 is fixedly arranged on the outer side of the slider 7, and a limiting spring 12 is arranged on the outer side of the mounting block 8, one end of the limiting spring 12 is connected to the mounting block 8, and the other end of the limiting spring 12 is connected to the inner groove 5 The second valve housing 2 is movably installed on the upper side of the first valve housing 1. A positioning frame 4 for docking with the sealing block 3 is fixedly arranged on the inner side of the first valve housing 1. Both sides of the positioning frame 4 are provided with positioning grooves 11 for docking with the positioning block 10. The limit spring 12 does not deform initially. When the slider 7 moves, it drives the mounting block 8 to move. The movement of the mounting block 8 stretches the limit spring 12. At this time, the limit spring 12 is deformed. When the slider 7 moves and resets, the elastic potential energy of the limit spring 12 is released, which can drive the positioning block 10 to be firmly clamped in the positioning groove 11, thereby ensuring the assembly stability of the first valve housing 1 and the second valve housing 2.

[0029] Specifically, a slide bar 6 is fixedly provided on the inner side of the inner groove 5 , and the slide bar 6 movably passes through the slider 7 . The slide bar 6 can limit the slider 7 , so that the slider 7 moves along the slide bar 6 , thereby improving the movement stability of the slider 7 .

[0030] Furthermore, a mounting rod 14 is movably provided on the inner side of the inner groove 5, connecting rods 15 are fixedly provided at both ends of the mounting rod 14, movable blocks 16 are fixedly provided at the outer ends of the two groups of connecting rods 15, and an arc block 13 for docking with the movable block 16 is fixedly provided on the outer side of the slider 7. When the mounting rod 14 moves, it can drive the two groups of movable blocks 16 to squeeze the two groups of arc blocks 13 at the same time, thereby facilitating the adjustment of the position of the positioning block 10 and facilitating the installation of the second valve housing 2.

[0031] It is worth noting that a limit block 17 for docking with the movable block 16 is fixedly arranged on the outside of the arc block 13. By setting the limit block 17, the movable block 16 can be limited, so that the movable block 16 can continuously squeeze the arc block 13 to ensure the normal use of the device.

[0032] It is worth noting that a movable rod 18 is fixedly arranged on the outside of the mounting rod 14. The movable rod 18 movably passes through the second valve housing 2 and extends to the outside. A movable hole 19 is penetrated on the inside of the second valve housing 2 for docking with the movable rod 18. A screwdriver can be conveniently inserted into the movable hole 19 to facilitate squeezing of the movable rod 18, thereby improving operational convenience.

[0033] In addition, a return spring 20 is sleeved on the outer side of the movable rod 18, one end of the return spring 20 is connected to the mounting rod 14, and the other end of the return spring 20 is connected to the inner groove 5. The return spring 20 does not deform initially. When the movable rod 18 is squeezed, the movable rod 18 moves to stretch the return spring 20, and the return spring 20 is deformed at this time. When the movable rod 18 is released, the elastic potential energy of the return spring 20 is released, thereby driving the movable block 16 to quickly separate from the arc block 13.

[0034] It must be mentioned that the outer sides of the second valve housing 2 and the sealing block 3 are penetrated by a through groove 21 for the docking connection block 9. The through groove 21 facilitates the movement of the positioning block 10 while ensuring the sealing between the first valve housing 1 and the second valve housing 2.

[0035] Working principle: First, fix the first valve housing 1 on the inner side of the oxygen concentrator, and then install the second valve housing 2 on the upper side of the first valve housing 1. During the installation process, press the movable rod 18 inward. When the movable rod 18 moves, it drives the installation rod 14 and the two sets of connecting rods 15 to move. When the connecting rod 15 moves, it drives the movable block 16 to move. The movable block 16 moves to squeeze the arc block 13. The arc block 13 is squeezed and drives the slider 7 to slide on the slide rod 6 and stretch the limit spring 12. Then, the first valve housing 1 is tightly pressed against the upper side of the second valve housing 2, so that the sealing block 3 presses the positioning frame 4, and then Then release the movable rod 18, so that the reset spring 20 resets and contracts. The elastic potential energy of the reset spring 20 is released to drive the movable rod 18 and the mounting rod 14 to move and reset. When the mounting rod 14 moves, it drives the movable block 16 to separate from the arc block 13. At this time, the limit spring 12 resets and contracts and drives the slider 7 to move and reset. When the slider 7 moves, it drives the connecting block 9 and the positioning block 10 to move until the positioning block 10 is inserted into the positioning groove 11 on the mounting frame 4, so that the first valve housing 1 and the second valve housing 2 can be quickly assembled and fixed, and it is also convenient to disassemble the first valve housing 1 and the second valve housing 2 later.
